Curt, The problems you may be experiencing with your createprocess intrinsic is that you recompiled your program into native mode using an item number list and an item list arrays setup for compatibility mode. For the compatibility mode compiler the item numbers array and items array are probably set up as PIC S9(4) COMP (16-bit) fields. When compiling in native mode these fields must be set up as PIC S9(9) COMP (32-bit) fields. This also is required if using item #2 for the PARM value in the item list array. Your problem with the error #17 is the alignment of the fields in the arrays. Tom Renz Consultant @ QualMed, Pueblo, Colorado 888-547-0938
